Well i have, after reading all the comments, come up with an easy solution that I feel emphasises Brikwars carnage. Bring a weapon. don't be a brikwussie. Quite brilliant, actually.
but in the case of not having a gun, he screams in frusturation and blows up, spraying acid-blood over his enemies.
Amen.

I know I'm necroing but this topic should stay alive, besides I'm using a heroic feat. personally I think that if a minifig is towering over another one the one who is about to be axed would be moving to suffer the most hilariously painful death possible instead of trying to fight back but if your minifig's a sissy he could punch which is punching someone once, this may give them a bloody nose but minifigs don't have them so it is futile. If your minifig is a hero who could incap an enemy in one punch then why is he punching instead of using the attacking minifig in a joust with the nearest wall
